Guerau IV de Cabrera (1196–1229) was a claimant to the County of Urgel during the reign of James I of Aragon. His uncle, Ponç III of Cabrera had married Marquesa, the daughter of Ermengol VII, in 1194. Marquesa’s father, Ermengol VII, was the son of Ermengol VI and his first wife, Arsenda of Cabrera. Through these familial connections to the House of Cabrera, Gerau claimed the County of Urgell.
